NCT ID: NCT01877928 Terminated - Clinical trials for Obstructive Sleep Apnea (OSA)

Post-extubation Boussignac CPAP System in Adults With Moderate to Severe Obstructive Sleep Apnea

Start date: June 2013
Phase: N/A
Study type: Interventional

The purpose of this study is to assess the efficacy of the Boussignac positive airway pressure system (a mask) applied immediately following post-operative extubation in improving lung function in patients with obstructive sleep apnea (OSA). Assessments will be done before surgery and then at 1, 2 and 24 hours following extubation and will be compared to standard care for perioperative airway support. The study aims to give a broader and more inclusive picture (than the current literature) in terms of whether the Boussignac CPAP system should be considered for utilization by anesthesiologists caring for surgical patients with OSA.

NCT ID: NCT01853891 Withdrawn - Clinical trials for Obstructive Sleep Apnea (OSA)

Dim Light at Night in Patients With Obstructive Sleep Apnea

Start date: February 2013
Phase: N/A
Study type: Interventional

With the advent of electricity, light at night has become a ubiquitous part of our society. The main purpose of this study is to determine whether sleeping with dim light (40 lux), the brightness of a night light) in your bedroom for 5 consecutive nights will result in increased markers of inflammation in the blood compared to sleeping in darkness during the night in patients with obstructive sleep apnea (OSA). A secondary aim is to examine the effects on insulin sensitivity, other blood proteins, and RNA molecules as a result of sleeping with dim light. RNA molecules are substances in blood that dictate what type of proteins the body should make.

NCT ID: NCT01642160 Completed - Clinical trials for Obstructive Sleep Apnea (OSA)

Continous Positive Airway Pressure (CPAP) Compliance Study

ICAN
Start date: July 2012
Phase: N/A
Study type: Interventional

Does an internet based text or email interaction and education improve CPAP compliance for patients with Obstructive sleep apnea (OSA) and reduce nursing intervention.

NCT ID: NCT01476917 Completed - Clinical trials for Obstructive Sleep Apnea (OSA)

The ATLAST Long-Term Study

Start date: November 2011
Phase: Phase 2/Phase 3
Study type: Interventional

The Study is a multi-center, prospective, open label, single-arm, three-month, long-term study of the Attune Sleep Apnea System for the treatment of obstructive sleep apnea (OSA). The objective of the study is to monitor long-term use of the Attune Sleep Apnea System.

NCT ID: NCT01249924 Completed - Clinical trials for Obstructive Sleep Apnea (OSA)

The Effectiveness of Perioperative CPAP to Reduce Obstructive Sleep Apnea Related Adverse Events

Start date: October 2009
Phase: N/A
Study type: Interventional

Objective of the study: To determine whether Perioperative Auto-CPAP treatment prevent postoperative worsening of OSA and improve nocturnal oxygen saturation in surgical patients with moderate and severe OSA.

NCT ID: NCT00965783 Completed - Obesity Clinical Trials

Predictors of the Metabolic Effect of Sleep Loss

SDBO
Start date: June 2007
Phase: N/A
Study type: Interventional

To test whether baseline levels of slow wave activity (SWA) during sleep are lower in obese adults, and even lower in persons with sleep disordered breathing (SDB) compared to lean adults. To compare levels of SWA in individuals in relation to their sleep time, blood pressure, heart rate, and markers of glucose metabolism.

NCT ID: NCT00945776 Completed - Clinical trials for Obstructive Sleep Apnea (OSA)

Weekly Phone Calls Versus Brief Patient Education to Improve Continuous Positive Airway Pressure (CPAP) Compliance

Start date: April 2008
Phase: Phase 2
Study type: Interventional

The purpose of this study is to compare the effects of three interventions on CPAP adherence.

NCT ID: NCT00850434 Completed - Clinical trials for Obstructive Sleep Apnea (OSA)

Improved Automatic CPAP Algorithm to Treat Obstructive Sleep Apnea (OSA)

Start date: November 2005
Phase: N/A
Study type: Interventional

The purpose of this study is to compare a modified AutoSet algorithm running on research hardware versus the traditional AutoSet algorithm running on an S7 AutoSet Spirit. The study will determine if the modified AutoSet algorithm reacts appropriately to obstructive apnoeas and hypopnoeas and provides suitable levels of positive airway pressure compared to the S7 AutoSet Spirit. The hypothesis is that the modified AutoSet algorithm will be more efficacious than the traditional AutoSet algorithm

NCT ID: NCT00834509 Completed - Clinical trials for Obstructive Sleep Apnea (OSA)

Biomarkers for Obstructive Sleep Apnea

BOSA
Start date: April 2008
Phase: N/A
Study type: Observational

The purpose of the study is to: - recruit subjects with untreated sleep apnea; assess overnight changes in their blood and urine chemicals - review the overnight changes in blood and urine chemicals after they have been treated for sleep apnea - assess the overnight changes in blood and urine chemicals in healthy individuals with no sleep problems - compare the amount of fat in the belly using a Magnetic Resonance Imaging (MRI) scanner on all subjects

NCT ID: NCT00773721 Completed - Clinical trials for Obstructive Sleep Apnea (OSA)

Foam Mask - Assessment of Bioburden in a New Mask Seal Material

Start date: October 2008
Phase: N/A
Study type: Interventional

Obstructive sleep apnoea (OSA) is characterised by a partial or complete collapse of the upper airway during sleep. The treatment of choice for OSA is Continuous Positive Airway Pressure (CPAP). CPAP acts as a positive airway splint, delivering a fixed positive airway pressure to the upper airway via a tube and mask. Compliance, however, to therapy requires that the mask is suitably comfortable so as not to disturb sleep. A key contributor to comfort is the seal component of the mask system. Current mask seals are mainly silicone elastomers, which though well understood and accepted, are often uncomfortable. It is proposed to replace the solid elastomer with a soft polymer foam. The foam is highly porous, and has open cells at its surface. It is therefore more likely to accumulate biological material with repeated use. The current (silicone) material does not present any problematic bioburden issues. Therefore it is important to investigate whether the foam will present bioburden problems to patients, within specified usage parameters. The aims of this study therefore are: 1. to observe the rate of bacterial accumulation on foam mask seal material (polyether polyurethane,) 2. to determine the replacement interval for a foam mask seal, and 3. assess the comfort and function of a foam mask seal.
